Just joined the DH club yesterday.
Cleaning and fixing a few issues, but going to be a very good game.

Does anyone know which backbox sockets are supposed to have blinker bulbs?
My understanding is that there are supposed to be four of them. All the sockets in mine have plain 555s in them.

Little Shop of Games has these also.

For LEDs, I color matched the playfield inserts. Left the playfield GI incandescent. Put warm whites in the backbox except for the blinkers (incandescent) and the ones behind the Dirty Harry lettering (red). I think it looks good, but that's all subjective.

I have what appears to be a recurring problem with the trap door. This is the vertical pop up door that allows the ball to pass from the shooter lane directly to the gun. It opens when you choose to plunge from the gun, and also in certain multiballs to get the ball directly to the gun.

Occasionally, there will be a ball jam in the lower gun area. This will cause the game to think that the trap door is stuck closed, when it really isn't. This is not a big deal, as the ball jam will clear as the gun loading kicker will cycle through and clear the jam.

The problem is that the trap door stuck closed error does not clear. The error will appear at startup and the game will play, but not allow the trap door to be activated. You cannot choose to plunge from the gun, and balls will not load to the gun from the trough in multiball.

The only way that I have found to clear the error is to do a factory reset. Not the biggest deal in the world, but wipes out all the settings and scores. Does not happen often, but annoying. A google search finds a couple of old RGP threads where factory reset is the only answer given. Anyone have a better answer?

Yeah, that's not normal. Sure you have the right coil on the launcher?

Flat - straight. No incline until it hits the flap for the tapered steel ramp. The tapered section is steep on the lower section then bends to almost flat on the tapered area.

Got a couple from Marco a while back, but they show out of stock now. Not sure who else might have them.
PPS has the decals if it's only the image that's bad.

Can you be a little more specific? Don't recall seeing something like this.

There are supposed to be 545 blinker bulbs behind the beacon lights on the bridge towers. They do not blink by CPU control.

It's certainly unique!

You've got to ask yourself one question: 'Do I feel lucky?'

Odd. looks like maybe the out of stock set is cut to match the target shape and the in stock set is cut square. Not sure about that though. Maybe emil Marco and ask.

Yeah, but the gun is just too cool to select the ramp shot. Gotta shoot the gun, just because it's there.

What are we looking for here?

Got it. Missed that at first.
Looks good!

I have a set waiting to get installed, but the disassembly and reassembly required looks to be a PITA. Might be a while until I get motivated enough.

I think his surprise is at the LOW price, not the HIGH price.

Suicide Jumper: Aren't you gonna try to grab me?

Harry Callahan: A friend of mine was up about 20 floors with a jumper a few years ago. The jumper grabbed him, they went off, 20 floors down. Just mashed 'em all to bits. You couldn't tell which legs were which, you couldn't tell which arms were which, it was a terrible mess. And I'll tell ya, I almost threw up myself. I'd just like your name and address, that's all.

I usually shoot the gun, just since it's cool. And my score isn't going to be great anyway.

Full manual is downloadable from IPDB as a PDF file.
Yea, that's likely your problem. The manual shows J115 as being part of the GI. Look at pages 3-10 and 3-29

Yikes! That sucks!

So who bought it?
It did look cool.

Edit: duh. Read the posts above first.
Congrats Cary!

Adjustment A.2.25 Instructional Speech - Turns those phrases on and off.

Cool. I was 99% that had to be it.
It's such an odd adjustment. Not sure any other games have anything similar.

That's happened more than once?
It looks correct, but I have never seen a ball stuck there. Not sure wbat it's hanging up on.
Maybe post a pic of tbat area without the ball.
Is the rolled over edge of the ramp cracked or bent at all?

One more possibility, but it looks like he's not doing Dirty Harry either, yet.

Cliffy does have hole protectors, just not ramp protectors.

I don't know what it means, but it looks more like an 8 with an underline to me.

Thanks for the heads up!
Just ordered one. It's going to nicely cover up the huge chunk of my ramp that's smashed off.

Maybe consider a partial shop job, where you only do the sections that you are comfortable with.
The rear section of the DH playfield has a lot going on.
I know I wouldn't want to tackle that as my first attempt.
If you do a full topside teardown, or even for a partial, take lots of notes and more pictures than you could possibly need.

Not gonna lie. The Harry head freaks me out a bit.

Comet and Cointaker quality is pretty similar, in my experience.
If Comet has what you want, they are generally less expensive.
Both are great to deal with.

Check the magnet and surrounding area of the playfield for damage.
Make sure the gun is working.

And, probably not.
Hope you find one. It's a great game.

Just to clarify, the game doesn't show the choices, or the flipper won't change which option you are selecting?

The police car and helicopter are both mods.
The backboard decal is also a mod. Factory is plain black.
Nice looking game!

He may just be busy. Got mine from him a while back. FYI, they ain't easy to install. Lots of stuff has to come apart.
